Portor is a relatively rare marble quarried in Italy and in Corsica. It is found in France, but very sparingly. A dark black color scattered with yellow grooves. Sometimes these grooves are grey, the marble is then know as Portagent.
The most beautiful Portor is dark black with deep yellow veins, like golden flames. Its name most likely comes from the town of Porto Venere on the Genoese coast where Louis XIV exploited quarries for the decoration of Versailles. Much used in the 17th, 18th and until the 20th century with the Art Deco style, for beautiful furniture, objets d’art and fireplace mantels.
